Description

Vorrichtung und Verfahren zur seitlichen Führung eines auf einem Rollgang transportierten Walzbandes Device and method for lateral guidance of a rolled strip transported on a roller table
Die Erfindung bezieht sich auf eine Vorrichtung zur seitlichen Führung eines auf einem Rollgang transportierten Walzbandes, vorzugsweise eines Warmbandes vor einer Wickelvorrichtung, mit beidseits des Walzbandes vorgesehenen parallelen ersten und zweiten Seitenführungen, die durch unabhängig voneinander verstellbare Verstellmittel aufeinander zu oder voneinander weg verschiebbar sind.The invention relates to a device for the lateral guidance of a rolled strip transported on a roller conveyor, preferably a hot strip in front of a winding device, provided on both sides of the rolled strip parallel first and second side guides which are displaceable by independently adjustable adjusting means to each other or away from each other.
Warmbandhaspeln sind am Ende von Warmbandstraßen angeordnet und haben die Funktion, Warmband nach dem Walzen zu Bunden aufzuwickeln. Das Band wird dabei unter Zugspannung aufgewickelt, um ein ausreichend fest gewickeltes und kantengerades Band zu erzeugen und ein Aufspringen des Bun- des nach dem Fertigwickeln zu vermeiden.Hot strip reels are arranged at the end of hot strip mills and have the function to wind hot strip after rolling into coils. The tape is wound up under tension in order to produce a sufficiently tightly wound and straight-edged strip and to avoid a break-up of the bundle after the finish-winding.
Während des Wickeins kann es unter bestimmten Umständen zum periodischen seitlichen Verlaufen des Walzbandes kommen. Dabei kann die Amplitude abklingen, während des gesamten Wickeins konstant bleiben oder anwachsen. Besonders bei hochfesten Güten oder niedrigen Wickeltemperaturen ist das periodische Verlaufen zu beobachten. Die Auslöser für den Beginn der Schwingungen sind vor allem Unplanheiten oder sogenannte „Säbel" am Bandkopf, während des Wickeins auftretender Zugverlust oder andere Störungen im Verlauf des Wickelvorgangs.During winding, under certain circumstances, the strip may periodically run sideways. The amplitude can decay, remain constant or increase during the entire Wickeins. Especially with high-strength grades or low coiling temperatures, the periodic bleeding is observed. The triggers for the beginning of the vibrations are above all unplanations or so-called "sabers" on the tape head, loss of traction occurring during winding or other disturbances in the course of the winding process.
Durch das periodische Verlaufen wird die Wickelqualität verschlechtert. Das Band wird nicht kantengerade gewickelt, es kommt zu losen Windungen und in extremen Fällen zu Instabilität und zum Abbruch des Wickelprozesses. Während des periodischen Verlaufens wandert das Walzband auf dem Bund, im Treiber und zwischen den Seitenführungen sinusförmig hin und her. Dabei kön- nen auf dem Bund Amplituden von 50 mm und mehr erreicht werden. Es treten hohe Kräfte in den Seitenführungen auf, was zu Kantenschäden und zum Umknicken der Bandkante führen kann.Due to the periodic bleeding the winding quality is deteriorated. The tape is not wound straight edge, it comes to loose turns and in extreme cases to instability and to stop the winding process. During the periodic course, the rolled strip travels sinusoidally on the collar, in the driver and between the side guides. In doing so, On the waistband amplitudes of 50 mm and more can be achieved. There are high forces in the side guides, which can lead to edge damage and buckling of the band edge.
Aus der DE 40 03 717 A1 ist eine Seitenführung für auf einem Rollgang trans- portiertes Walzband, vorzugsweise Warmband vor einem Haspel, bekannt. Es sind beidseits des Walzbandes aufeinander zu bzw. voneinander weg verschiebbare Führungslineale oder Seitenführungen vorgesehen, die in einem ersten Schritt grob vorpositionierbar und in einem zweiten Schritt an das Walzband anpressbar sind. Hierzu werden Hydraulikzylinder eingesetzt, die in dem zweiten Schritt den erforderlichen Anpressdruck aufzubringen vermögen. Die Hydraulikzylinder bewirken die Verschiebung der Führungslineale sowohl während des ersten als auch während des zweiten Schrittes. Für die Steuerung der Hydraulikzylinder ist eine Regelvorrichtung vorgesehen, die über die ihr als Stellglieder nachgeordneten Hydraulikzylinder während des ersten Schrittes die Führungslineale aus einer zurückgezogenen Ausgangsposition auf eine vorgebbare Position vorschieben. Während des zweiten Schrittes wird mindestens einer der Hydraulikzylinder sowohl positions- als auch kraftgeregelt.DE 40 03 717 A1 discloses a side guide for rolled strip transported on a roller table, preferably hot strip in front of a reel. There are on both sides of the rolled strip to each other or mutually displaceable guide rulers or side guides provided, which are coarsely prepositioned in a first step and in a second step to the rolled strip can be pressed. For this purpose, hydraulic cylinders are used, which are able to apply the required contact pressure in the second step. The hydraulic cylinders cause the displacement of the guide rulers both during the first and during the second step. For the control of the hydraulic cylinder, a control device is provided which advance the guide rulers from a retracted starting position to a predeterminable position during the first step via the hydraulic cylinders arranged downstream of them as actuators. During the second step, at least one of the hydraulic cylinders is both positionally and force-controlled.
Auch aus der WO 2002 030587 A1 ist eine Vorrichtung zum Führen eines Me- tallstreifens zu einem Haspel bekannt, bei der seitliche Führungslineale zum Einsatz kommen. In Laufrichtung des Metallbandes sind auf beiden Seiten jeweils ein erstes und ein zweites Führungslineal vorgesehen. Die Positionen der zweiten Führungslineale bezüglich des Metallbandes werden unabhängig von den Positionen der ersten Führungslineale durch Positionsregler geregelt.A device for guiding a metal strip to a reel is also known from WO 2002 030587 A1, in which lateral guide rulers are used. In the direction of the metal strip a first and a second guide rule are provided on both sides. The positions of the second guide rulers with respect to the metal strip are controlled by position controllers independently of the positions of the first guide rulers.
Es ist die Aufgabe der Erfindung, eine verbesserte Vorrichtung zur seitlichen Führung eines auf einem Rollgang transportierten Walzbandes zur Verfügung zu stellen.It is the object of the invention to provide an improved apparatus for laterally guiding a rolled strip transported on a roller table.
Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der eingangs ge- nannten Art dadurch gelöst, dass eine Regeleinrichtung zur Dämpfung des periodischen Verlaufens des Walzbandes vorgesehen ist, der als Eingangsgrößen bei der Führung des Walzbandes wirkende Kräfte und/oder Positionen der Führungslineale und/oder des Walzbandes zuführbar sind und dass die Regeleinrichtung aufgrund der gemessenen Eingangsgrößen die Positionen der Füh- rungslineale und/oder Kräfte regelt, die die Seitenführungen auf das Walzband ausüben.According to the invention, this object is achieved in a device of the kind described in the opening paragraph. Type mentioned solved by the fact that a control device is provided for damping the periodic running of the rolled strip, which can be fed as input variables in the leadership of the rolling strip forces and / or positions of the guide rulers and / or the rolled strip and that the control device due to the measured input variables Positions of the guide rulers and / or forces that exert the side guides on the rolled strip.
Der Kern der Erfindung besteht darin, dass eine Vorrichtung zur Dämpfung und Vermeidung des seitlichen Verlaufens des Metallbandes geschaffen wird. Damit wird der Wickelprozess stabilisiert. Als Stellsystem werden in an sich bekannter Weise die Seitenführungen oder Führungslineals im Bereich vor dem Wickelhaspel eingesetzt. Die Seitenführungen lassen sich senkrecht in Bezug auf das Wickelband verstellen, um ihre Positionen an die Breite des jeweils zu wickelnden Bandes anzupassen.The essence of the invention is that a device for damping and avoiding the lateral running of the metal strip is provided. This stabilizes the winding process. As a control system, the side guides or guide rulers are used in the area before the winding reel in a conventional manner. The side guides can be adjusted vertically with respect to the winding tape to adjust their positions to the width of the respective tape to be wound.

Mit Vorteil wird eine Differenzkraft aus den jeweils auf die beiden Führungsline- ale wirkenden Kräften gewonnnen und dann der Regeleinrichtung zugeführt.Advantageously, a differential force is obtained from the forces acting on the two guide lines and then supplied to the control device.

Zusätzlich lässt sich mit Vorteil vorsehen, dass der Regeleinrichtung die gemessene Bandmittenposition des Walzbandes und/oder ein gemessener Differenzzug des Walzbandes, insbesondere im Bereich des Haspels, als Eingangsgrößen zugeführt werden. Von Vorteil ist es außerdem, wenn die Regeleinrichtung einen Regler umfasst, dem die Kräfte, die die beiden Führungslineale auf das Walzband ausüben, zuführbar sind und die aus diesen jeweils Wegsignale für die beiden Führungslineale erzeugt.In addition, it can advantageously be provided that the control device is supplied with the measured strip center position of the rolled strip and / or a measured difference draft of the rolled strip, in particular in the region of the reel, as input variables. It is also advantageous if the control device comprises a regulator, to which the forces exerted by the two guide rulers on the rolled strip can be fed and which generates path signals for the two guide rulers from these.
Zusätzlich ist es von Vorteil, wenn dem Regler für die beiden Seiten des Walzbandes ein erster bzw. ein zweiter Positionsregler nachgeordnet sind, wobei dem ersten Positionsregler die Summe aus dem von dem Regler erzeugten Wegsignal und der Differenz zwischen dem Positionssollwert und dem Positionsistwert des ersten Führungslineals und dem zweiten Positionsregler die Dif- ferenz aus dem von dem Regler erzeugten Wegsignal und der Differenz zwischen dem Positionssollwert und dem Positionsistwert des zweiten Führungslineals zuführbar ist.In addition, it is advantageous if the controller for the two sides of the rolled strip, a first or a second position controller are arranged, wherein the first position controller, the sum of the path signal generated by the controller and the difference between the position setpoint and the actual position of the first guide ruler and the second position controller can be fed with the difference from the path signal generated by the controller and the difference between the position setpoint and the actual position value of the second guide rule.
Vorzugsweise erzeugen die beiden Positionsregler jeweils Ventilsollwerte für Hydraulikzylinder zur Betätigung der Führungssignale oder Seitenführungen.Preferably, the two position controllers respectively generate valve setpoints for hydraulic cylinders for actuating the guide signals or side guides.
Die Erfindung bezieht sich auch auf ein Verfahren zur seitlichen Führung eines auf einem Rollgang transportierten Walzbandes, vorzugsweise eines Warmbandes vor einer Wickelvorrichtung, mit beidseits des Walzbandes vorgesehe- nen parallelen ersten und zweiten Seitenführungen, die durch unabhängig voneinander verstellbare Verstellmittel aufeinander zu oder voneinander weg verschoben werden.The invention also relates to a method for laterally guiding a rolled strip transported on a roller conveyor, preferably a hot strip in front of a winding device, with parallel first and second side guides provided on both sides of the rolled strip, which are displaced toward or away from each other by adjusting means which are independently adjustable become.

Ein Metallbandhaspel 1 (Fig. 1) dient zum Aufwickeln eines Metallbandes 2, insbesondere eines Warmbandes, mittels einer Wickelvorrichtung 3, auf die das Metallband 2 in Form eines Bundes 4 auf einen Dorn 5 aufgewickelt werden soll. Das Metallband 2 wird über einen Seitenführungsbereich 6 geführt, durch einen eine Treiberunterrolle 7 und eine Treiberoberrolle 8 umfassenden Treiber gezogen und schließlich auf der Wickelvorrichtung 3 aufgewickelt. Während des Wickelprozesses kann es unter bestimmten Umständen zu einem periodischen seitlichen Verlaufen des Walzbandes 2 kommen, d. h. das Metallband 2 wird nicht mittig und kantengerade auf dem Wickeldorn 5 der Wickelvorrichtung 3 aufgewickelt, sondern weicht seitlich von der mittleren Position ab. Beispielsweise entstehen periodische Abweichungen von der mittleren Position auf dem Wickeldorn 5. Dabei kann die Amplitude des seitlichen Versatzes des Metallbandes 2 gegenüber der gewünschten mittleren Stellung während des Wickelvorgangs abklingen (Fig. 2), während des gesamten Wickelvorgangs konstant bleiben (Fig. 3) oder während des Wickeivorgangs anwachsen (Fig. 4).A metal tape reel 1 (FIG. 1) serves to wind up a metal strip 2, in particular a hot strip, by means of a winding device 3, onto which the metal strip 2 in the form of a collar 4 is to be wound onto a mandrel 5. The metal strip 2 is guided over a side guide region 6, pulled by a driver comprising a driver lower roller 7 and a driver upper roller 8, and finally wound on the winding device 3. During the winding process, under certain circumstances, a periodic lateral running of the rolled strip 2 may occur, ie the metal strip 2 is not wound centrally and edgewise on the winding mandrel 5 of the winding device 3, but deviates laterally from the middle position. For example, periodic deviations from the mean position on the winding mandrel 5 occur. The amplitude of the lateral offset of the metal strip 2 can decay relative to the desired middle position during the winding process (FIG. 2), remain constant during the entire winding process (FIG. 3) or grow during the Wickeivorgangs (Fig. 4).
Erfindungsgemäß umfasst der Metallbandhaspel 1 im Seitenführungsbereich 6 (Fig. 5) auf beiden Seiten, d. h. auf der Bedienseite wie auf der Antriebsseite, hydraulisch betätigte Anstellzylinder 9, 10, um Seitenführungen 11 , 12 entsprechend der gewünschten Position des Metallbandes 2 verstellen zu können, wo- bei der Anstellzylinder 9 auf der Bedienseite und der Anstellzylinder 10 auf der Antriebsseite angeordnet ist. Das Metallband 2 läuft in diesem Bereich über Rollen 13.According to the invention, the metal tape reel 1 in the side guide region 6 (FIG. 5) comprises on both sides, i. H. on the operating side as on the drive side, hydraulically actuated adjusting cylinder 9, 10 in order to adjust side guides 11, 12 according to the desired position of the metal strip 2, wherein the adjusting cylinder 9 is arranged on the operating side and the adjusting cylinder 10 on the drive side. The metal strip 2 passes over rollers 13 in this area.
Gemäß der Erfindung werden folgende Größen in den Regelungsvorgang ein- bezogen:According to the invention, the following variables are included in the control process:

Metallbandes 2,Metal band 2,
FSAS Kraft der Seitenführung 12 auf der Antriebsseite auf die Seitenkante des Metallbandes 2,FSAS force of the side guide 12 on the drive side on the side edge of the metal strip 2,
ΔSD Differenzposition als Zusatzsollwert,ΔSD difference position as additional setpoint,
SBSREF Positionssollwert der Seitenführung 11 auf der Bedienseite,SBSREF position setpoint of the side guide 11 on the operating side,
SBSACT Positionsistwert der Seitenführung 11 auf der Bedienseite,SBSACT position actual value of the lateral guide 11 on the operating side,
SASREF Positionssollwert der Seitenführung 12 auf der Antriebsseite, SASACT Positionsistwert der Seitenführung 12 auf der Antriebsseite, yvAS Ventilsollwert eines Ventils des Anstellzylinders 9 auf der Bedienseite und yvßs Ventilsollwert eines Ventils des Anstellzylinders 10 auf der Betriebsseite.SASREF position setpoint of the lateral guide 12 on the drive side, SASACT actual position of the lateral guide 12 on the drive side, yv AS Valve setpoint of a valve of the positioning cylinder 9 on the operating side and yv β s valve setpoint of a valve of the positioning cylinder 10 on the operating side.
Einem Regler 14 (Fig. 6) werden die beiden Kraftwerte FSBS der Seitenführung 11 auf der Bedienseite und FSAS der Seitenführung 12 auf der Antriebsseite als Eingangswerte zugeführt. Der Regler 14 gewinnt aus der Differenz einen Positionswert, nämlich die Differenzposition ΔSD- Andererseits wird aus der Differenz aus dem Positionssollwert SASREF der Seitenführung 12 und dem Positionsist- wert SASACT der Seitenführung 12 ein erster Positionswert gewonnen, der mit dem Wert ΔsD aufsummiert wird und einem Positionsregler 15 für die Antriebsseite zugeführt, der daraus den Ventilsollwert yvAS erzeugt, um den Anstellzy- linder 9 zu betätigen.A controller 14 (FIG. 6) is supplied with the two force values FSBS of the side guide 11 on the operating side and F S AS of the side guide 12 on the drive side as input values. On the other hand, a first position value is obtained from the difference between the position setpoint SA S REF of the lateral guide 12 and the position actual value SA S A C T of the lateral guide 12, which value is obtained from the difference Value Δs D is summed up and fed to a position controller 15 for the drive side, which generates the valve setpoint value yv AS therefrom in order to actuate the setting cylinder 9.
Andererseits wird der von dem Regler 14 gewonnene Wert ΔSD von einem zweiten Positionswert subtrahiert, der aus der Differenz aus dem Positionssollwert SBSREF der Seitenführung 11 und dem Positionsistwert SBSACT der Seitenführung 11 erzeugt wird. Der durch die Subtraktion des Wertes ΔSD erzeugte Wert wird einem Positionsregler 16 für die Bedienseite zugeführt, der daraus den Ventil- sollwert YBAS erzeugt, um den Anstellzylinder 10 zu betätigen. Auf diese Weise wird eine individuelle Regelung der Positionen der beiden Anstellzylinder 9, 10 ermöglicht. On the other hand, the value ΔSD obtained by the controller 14 is subtracted from a second position value generated from the difference between the position command value SBSREF of the side guide 11 and the actual position value SBSACT of the side guide 11. The value generated by the subtraction of the value .DELTA.SD is fed to a position controller 16 for the operating side, which generates therefrom the valve setpoint Y B AS, in order to actuate the setting cylinder 10. In this way, an individual regulation of the positions of the two adjusting cylinders 9, 10 is made possible.
